Django: Save inline form before run action

Question

I'm using a django-inline-actions package for let end-users run actions in admin inlines. But it's no matter what exactly using for action button, i can implement it by hand (like this, for example), behavior will still the same.

This look as:

As provided by the django engine, the user does things like:

1. Fill inline
2. Click Save and continue button
3. Click action button

and he repeating it again and again, becouse users use action buttons very often.

Is there any possibility for omit step 2?

I think, it can be javascript hook, which capture click event, save inline data with ajax, and then run action. But i have no idea how implement it.

May be there is another way to do it?
